neuropil

 [noor´ro-pil]
a dense feltwork of interwoven cytoplasmic processes of nerve cells (dendrites and axons) and of neuroglial cells in the central nervous system and some parts of the peripheral nervous system.

neu·ro·pil

, neuropile (nū'rō-pil, -pīl),
The complex, feltlike net of axonal, dendritic, and glial arborizations; forms the bulk of the central nervous system's gray matter, and in which the nerve cell bodies lie embedded.
[neuro- + G. pilos, felt]

neu·ro·pil

, neuropile (nūr'ō-pil, -pīl)
The complex, feltlike net of axonal, dendritic, and glial arborizations that forms most of the gray matter of the central nervous system, and in which the nerve cell bodies lie embedded.
[neuro- + G. pilos, felt]

neuropil

the mass of DENDRITES and AXONS surrounding the cell bodies of the central nervous system.

Principal and secondary visual inputs are processed in separate pathways with distinct neuropil regions, including separate laminae and medullae (Strausfeld and Barth, 1993; Strausfeld et al., 1993; Long, 2016).
The ir nerve fibers were detected throughout the neuropils of the ganglion, especially in the dorsal and ventral horns (Fig.
"In branchiopods, there are always only two visual neuropils and they are not linked by crossing fibers.
In these animals, such chemosensory information is conveyed to the central nervous system through two anatomically distinct but parallel pathways: the aesthetascolfactory lobe pathway and the non-aesthetasc-lateral antennular neuropil pathway, which are reciprocally connected by local olfactory interneurons (Schmidt et al., 1992; Schmidt and Ache.
The immunoreactivity of both types of nerve fibers were also found throughout the neuropils of the ganglia, especially in the dorsal and ventral horn regions, (Fig.
A semi-thin histological analysis with toluidine blue staining shows that the brain consists of a central core neuropil and peripherally situated cell body regions with a pair of dorsal globuli groups (Loesel and Heuer, 2010; Fig.
Antennular withdrawal motoneurons in the lateral antennular neuropil of Callinectes sapidus.
Notable features in the ventral and lateral nerve cords are some large, distinct ganglionic masses with ovoid neuropils in the head region (Fig.
6) and the ganglion neuropils and connectives/commissures were characterized by an intensive GLU-LIR innervation from the early juvenile stages (Fig.
Crustacean ORN axons course within the antennular nerve to a specific, ipsilateral region of the deutocerebrum, the olfactory lobe (OL), characterized in all decapods (as in the immediate central nervous targets of olfactory axons in all other arthropods as well as in vertebrates) by compartmentalized aggregations of neuropil referred to as glomeruli.
Microanatomical studies on the optic neuropiles of an isopod, Ligia exotica Roux (Crustacea).
In the CG, as in crustacean ganglia generally, synaptic interactions occur in complex neuropils formed by collateral processes and branches from axons (Alexandrowicz, 1932, 1934, 1952; Obsawn, 1972; Aizu, 1975; Hawkins and Howse, 1978; Mirolli et at., 1987; Morganelli and Sherman, 1987).
